Patented "Mar. 21, 1933 UNITED STATES ARTHUR A. JOHNSON, OF BBIDGEPOBT, CONNEGTIOUT HANIFOLDING Application nae September a, mi. Serial No. 580,968.

This invention relates to manifolding, and more particularly, to a provision of a pile of continuous superposed record and interleaved transfer strips for use in typewriting machines and the like.

In practice in electrically operated typewriters and the like where a number of co ies. are to be made, it has been proposed be ore to provide superposed record strips having between them carbon or transfer strips running with the record strips, the record strips containing a succession of forms, usually printed, and between adjacent forms in a strip there is provided a designated tear-off point along which the strips may be severed into sheet or formllengths. In my copending application, Serial No. 332,063, filed J anuary 12, 1929, I have disclosed means for facilitating the stripping of the carbon or transfer sheets from a severed set of superposed record and transfer sheets after the writing operations have been completed.

In one of the'forms of the invention illustrated in said application, this is accom plished by having lines of perforations, which are located between forms at the tearofi line, offset longitudinally in the record and transfer strips respectively, so that the record strips of a set project beyond the carbon strip: at one end and the carbon strips project yond the record strips at the other end to form finger-grips. This requires that the lines of perforations in the record'and transfer strips respectively be offset depthwise of the pile and in a direction longitudi nally of the pile.-

In an application of Carl W. Brenn, Serial No. 528,528, filed A ril 8, 1931, now Patent No. 1,821,905 grante September 1, 1931, provision is made for facilitating stripping of the carbons from the record sheets of a severed set of sheets by offsetting the transfer and record strips laterally in the pile. These offset and projecting portions constitute feeding bands and have, in the preferred form, rows of pinwheel engaging apertures by means of which the strips are advanced over the writing surface of the typewriter 0 or like machine. The apertured feeding bands on the record strips were at one side of the pile while those on the carbon strips were at the other side of the pile. Accordingly, each kind of strips engaged only one of the pinwheels.- An ob'ect of this invention is to provide a pile o manifolding strips in which the apertured feeding bands may be at both lateral edges of both the record and carbon strips, or the apertured feedin bands of both 9 I kinds of strips may be at on y one and the same side of the pile. This is accomplished,

in the preferred form of my invention, by making only the edge portions of the feeding bands pro ect instead of major portions thereof, as in said Brenn application, Serial No. 528,528.

In carrying out my present invention, the record and transfer strips may be offset in the manufacture of the pile and may be connected together by staples or the like in this offset condition, Or, if desired, the strips may have their edges in registry depthwise of the pile while in pack form, m which case the in-apertures in the feedinf, bands on the different kinds of strips won (1 be out of registration In this form of the inventlon, thestrips are left free to be shifted laterally when introduced to the typewriter to offset the ed es of the strips and at the same time so align 51o pin-apertures. This ofiset relation is maintained because of the engagement of the pinwheel pins-in the ali ed a rtures and the shifting of the trans er, an record strips respectively is efiected by the pinwheels 55 and as a result of the feeding operation and takes places in a free stretch of the pile leading from the pack tothe platen. This arrangement. and method is described vand claimed in m application Serial No. 560,967 filed Septemiier 3, 1931, covering. a companion part of this invention.

Other features and advantages will hereinafter appear. 1

As shown in the accompanying drawings, the pile of manifolding strips may comprise record strips 10 and interleaved carbon strips lines 13, preferably 11 which are continuous in form and which are placed one above the other in superposed relation. For convenience in shipping and handling, this pile of strips is preferably zigzag folded to form a pack or block 12, as shown in Fig. 1, from which the leading end may be lifted to be inserted in a typewriter or like machine.

The zigzag folding of the pile of strips 10 and 11 is facilitated by transverse weakening rforations, in some or all of the strips an these further serve as lines of severance along which the ile of strips may be severed to form sets 0 interleaved record sheets 10a and carbon sheets 11a, shown in Figs. 3 and 6.

In cases where it was desired to use the pile of strips 10 and 11 in a telegraphic ty writer havlng pinwheel feeding devices dr keeping the pile in strict coordination with the platens o the sending and receiving machines, it was heretofore customary to provide the record strips 10 with lateral margins projecting beyond the adjacent edges ofthe carbon strips so as to constitute feeding bands having apertures for engagingpins 14 on the typewriter-platen 15, see Fig. 6.

In the application of Carl W. Brenn, Serial N 0. 528,528, now Patent No. 1,821,905, granted September 1, 1931, the stripping of the transfer sheets from the record sheets from a severed'set of sheets was facilitated by provided feeding bands on the transfer strips at one .side of the pile while the feeding bands for the record strips were provided at the other side of the pile with both sets of feeding bands projecting beyond the adjacent edges of the other strips. With this arrangement,

while the transfer strips haveat each side margin feeding bands 17, each feeding band 16 and 17 having pin-engaging apertures 19. The strips 10 and 11 may be so superposed that the pinwheel apertures 19 are in registry, as shown in Fig. 2, and the strips may be secured together in this relation by staples 18 located on the lines of severance 13.

The pile of strips is led around the typewriter platen so that the pins 14 thereon engage the apertures 19 on the strips. After they are written upon, the strips may be torn along the lines of perforations 13 to form a set of superposed record sheets 10a and transfer sheets 11a as shown in Fig. 3. At this time it 10a and 110 from each other, instead of having the entire feeding band projecting beyond the adjacent edge of the other kind of strip as proposed in the illustrated embodiment of the invention of the Brenn Patent No. 1,821",- 905, above referred to, the present invention merely makes the feeding bands 16 and 17 of the record and transfer strips respectively wider at opposite sides of the pile. That is to say, as shown in Fig. 2, the feeding band 16 at the left-hand side of the pile has an extension 20 reaching beyond the adjacent edge 21 of the transfer strip while at the righthand side of the pile the feeding bands 17 on the transfer strips have extensions 22 prorecord strips. Hence, in the severed set of sheets 10a and 11a, the extensions 20 and 22 are free to be gripped separately by the operators hands and to be stripped apart by a spreading movement of the operators hands while so gripping the extensions.

If desired, the apertures 19 at either side of the pile in both the record and transfer strips may be omitted in which case the strips may be fed and controlled by the apertures at only one side of the pile. uch an arrangement is shown in Fig. 8, but even in this case unapertured edges of the strips are preferably ofl'set laterally, the transfer strips having extensions 22a reaching beyond the adjacent edge 23a of the record strip.

As taught in my copending application Serial No. 560,967, filed September 3, 1931,

of which this application is a companion part, the lateral edges of the transfer strips and record strips may be in alignment in the pack as shown in Fig. 4. When so arranged. the manufacture of-the pack is facilitated because ordinary guiding means may be employed to control the strips in the feeding and folding operations.

\Vhen the pack is so formed, the apertures 19 in the transfer and record strips respectively are offset laterally depthwise of the pile.

In this form of the invention, the strips 10 and 11 are not secured together by a staple, but are left free so that in introducing the strips in the typewriter, the free stretch of strips 24 between the pack and the typewriter platen 15 may have the transfer strips and record strips shifted laterally to bring the apertures 19 on the two kinds of strips into registry and cause the extensions 20 and 22 to project beyond the adjacent edges 21 and 23 respectively, to form the finger-grips f'or stripping purposes. The leading ends of the strips are placed on the typewriter platen with the pins 14 extending into the registering apertures 19 in this condition and, as the feeding of the pile of strips continues, successive portions of the strips are offset laterally as they approach the typewriter platen and as a result of the feeding operation.

Variations and modifications may be made within the scope of this invention and portions of the improvements may be used withoutothers.

Having thus described the invention, what is claimed as new and for which it is desired to obtain Letters Patent, is

1. A pile of superposed and interleaved record and transfer strips each having. at each side margin a feeding band provided with a row of pinwheel-engaging apertures, the feeding bands of the record strips at one side of the pile projecting beyond the adjacent edges of the transfer strips and the feeding bands of the transfer strips at the other side of the pile projecting beyond the adjacent edges of the record strips, the projecting feeding bands forming finger-grips for stripping purposes.

2. A pile of superposed and interleaved record and transfer strips each having at one side margin of the pile a feeding band provided with a row of pinwheel-en aging apertures, the edges of the feeding ands of the record strips being ofl'set laterally of the pile with relation to the edges of the feeding bands of the transfer strips so that the feeding bands of one kind of strips project beyond the feeding bands of the other kind of strips to form finger-grips for stripping purposes.

3. A pile of superposed and interleaved record and transfer strips each having at one side margin of the pile a feeding band provided with a row of Pinwheel-engaging apertures, the edges of the feeding bands of the
